And the switch is down , you must stop from racing to handle it . It has a switch on the handlebar ? If not , very useless .
"- Oh, a bumpy trail ahead , let's turn it on !" and you stop and lose the wave,

I think this is a huge step .And blootooth it's ok , you just want to aim or see if the movie is good .
Also GoPro will have a lcd backpack with a speaker .I can't really make my mind and buy one of them .
The main difference is the GPS . GoPro doesn't have it .
What should I buy ? Contour GPS or Hero ?
Thanks
